1978年香港一圆错版。以较轻坯饼铸打(5.71克)。女王肖像完整,但边缘刻槽较浅,说明坯饼厚度正确但直径过小。HONG KONG. Dollar, 1978. Mint Error. PCGS MS-63 Gold Shield.。5.71 gms. KM-43; Mars-C43. Struck on light weight planchet (5.71 gms.). The queens portrait is fully struck but the edge reeding is weak, suggesting that the planchet was the correct thickness but too small in diameter.。
